Technical problem in withdrawing drugs

Here i am in my final year practical. Just started to serve medication. Yesterday,
i found a technical problem in withdrawing the drugs from vials.
Prescription: 2g IV cloxacillin
available: 500mg per vail
so, i open 4 vails to dilute each with 2ml water for injection each.
NOw, i suppose to change my needle how many times?
That day, i change 6 times.
4 needle for different vails. the last 5th one, i used to withdraw all diluted cloxacillin. THe last one i use to inject to the 100ml N/S.
i doesn't feel good with the technique, am i doing it right or there is a better solution?

Good grief. Don't you have a pharmacy?

Quote from RescueNinjaI don't know anyone that switches needles between vials just for reconstitution of medication. As long as you don't touch the needle to anything other than the stopper (which should be wiped with alcohol if not freshly opened) your needle will remain sterile. Then after you reconstitute and withdraw all the medication change the needle (do you not use needless/plastic devices?) before infusing. So 2 needles total.Here is a video showing you how to prepare meds. She is only using 1 vial, but you'll notice that she does not change her needle in between the N/S and the medication.http://www.youtube.com/watch?v=8ECYuiHFObU

Quote from Student CherylPharmacy doesn't prepare the infusion for us in my hospital. Furthermore, cloxacillin half life is 30minutes to an hours only. Sometimes, i saw my staff nurse even left the antibiotic aside for quite a while.

I think there is some confusion about the type of needle being used to access the vials. At my hospital, you would have to use a different needle for each vial. This is because we use "needle-less vial access cannulas", when you remove one from a vial, the part with the sharp point gets left in the vial, meaning you'll need to replace it before moving on to the next vial. Are the majority of hospitals still using sharps for accessing vials?

Quote from PetiteOpRNHalf life is the time it takes for the bioavailability to decrease to 50% after the patient has been administered the drug. The length of time between reconstitution and injection should not affect half life. In fact, for some antibiotics that foam quite a bit, the recommendation is to reconstitute and let sit for 20 minutes instead of shaking it.And 2 needles is plenty.

"needle-less vial access cannulas" - HamsterRNI call those "harpoons" and I don't like them.

Quote from Student CherylIn my country, Yes. Majority of the hospitals still using sharp to access the vials. In my university hospital, i didn't see any plastic device present. So, total how many needle will you use in my condition with reference to my question.
